Abstract

The invention relates to a steam pressure vessel consisting of a receptacle and a lid, said receptacle and lid each having a long handle and being designed to be tightly joined together by way of overlapping peripheral segments along the lines of a bayonet catch, with the interposition of a sealing ring between the edge of the pot and the edge of the lid, characterized by the combination of at least two closing and opening safety devices, in which case a first safety device comprises a safety valve, the body of which is held in the open position by a spring-biased slide (10) until receptacle and lid are brought into the locked position by turning the two handles (1, 11) so that they lie one on top of the other with the coordinating peripheral segments completely overlapping, and a second safety device raises the sealing ring from the edge of the lid by means of a safety element (safety cam 7) spring-biased in the open position until receptacle and lid are brought into the locked position.
